VULCANIZER.

Specification of Letters Patent.

Application led August 9, 1912d Patented Sept. 24, 1912. serial No. 714,259.

To all whom t may concern Be' it known that l, EDWIN C. McGraw, a citizen of the United States, residing at last Palestina'in the county ot Columbiana and State et Oli-io, have invented certain new and useful Improvements in Vulcanizers; and I do hereby declare the :following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appcrtains to make and use the same..

My invention relates to a vuleanizing ap'- paratus especially adapted for applying patches to rubber tires or tubes. Its object is to provide a simple and cheap apparatus suitable either for the road or the shop, and which will require no skill to use and involve no regulation beyond the simple indication of the amount of fuel to be consinned. invented what is, in effect, an open self-regulated liquid fuel heater, comprising substam tially a receptacle tor fluent fuel, heat distributing members within the receptacle to communicate the heat of the fuel to the bottom of' the receptacle, means for clamping the object to be treated against the bottom ot the receptacle, and a cup adapted to be placed in the receptacle and itself serve as a receptacle tor a fluent fuel when the vulcanizer is to be applied in a substantially vertical position.

ln the accompanying drawings, Figure l is a perspective view ot' a vulcanizer in a forni especially adapted tor repairing punctures or similar tears or cuts in a tube or tire; Fig. 2 is a central sectional view taken through Fig. l and showing a patch being applied; Fig. 3 is a plan view showing the removable cup in place, the vulcanizer being indicated as apiiilied to the tread ot a tire; Fig. Ll is a perspective detail ot the removable cup.

ln the drawings 5 represents a base, in the form illustrated a circulanslmped plate with extending wings (l on each side. lFreni. each of these wings rises a threaded post 7.

8 is a basin or receptacle preferably some what heavier at the bottom oi. the outer wall than at the top, as indicated at l), in Fig. 2, and having the bottom slightly concaved on the lower surface for the purpose of fitting a patch as illustrated in Fig. i2.

1l represents a web-strengthened wing eX- To accomplish this object I have -in Fig. 2.

tending from each side of the receptacle 8, each wing having at the end a knuckle 12 with a recess 12S which permits each knuckle to embrace a post 7, the receptacle being clamped upon the base in an obvious manner by means of tlnnnbauxts lll. I have shown the knuckles as reversed on opposite sides S0 that the receptacle may be swung about readily on the base. This and other details of construction are, however, merely preferred :toi-nis, it being obvious that there may be many variations in the torni, shape and size ol such inci/.lental parts.

lVithin the receptacle 8 and secured to or integral with thc bottom l0 of the receptacle are a series of conical radiator pins l5, this being a preferred -,term ot' hcat-distributing member to provide l'or the uniform distribution through the bottom of the receptacle of the heat nnparted by the iames oi the liquid Atuel which is indicated by dotted lines on the bottom ol' the receptacle 8, as shown 1G represents a tire tube clamped against the bottom olf the receptacle 8.

1T represents a rubber patch in place and 18 represents the puncture or the center of a cut in the tire. ln this case an additional amount ot' soft or quick-curing rubber such as is used in this repair workis indicated at the point 1S.

In Figs. 23 and el I have illustrated a removable segmental-shaped cup 20, preferably ol copper or some suitable metal, which l may put ln place anywhere in the space bet-ween the pinsand the walls of the receptaclc,A I have shown the cup as o't coinpm'atively small size. lt will be readily un'- derstood that l may put the rows of pins closer vtogether lo make more room, or at the top and bottom and sides, if desired, I may put a single piu closer to the center so as to make room t'or a larger cup, it being nnderstood that the cup shown is merely by way of illustration. This cup is to be used when the vulcanizer is applied to a tire on thc wheel, ilor example, or when the vulcanizer is used in any other than a substantially horizontal position. lt may, ot' course, remain in the vulcanizer but it isintended that it shall be removed and usedonly when desired t'or the especial purposes indicated.

lVhcn the cup 20 is used the flames will act upon the heat distributing members car- 'rfing the heat down through the bottom of thus lower the temperature so that the furil receptaclel for a, `fluent fuel having heat-dis# ous burning does not unduly .heet-,the re ceptacle. Then as the' rece teole cools 'the point is reached where the ames are again y' u burning at the ylower levels endere again more effectively heating the" bottom of the receptacle through the multiple points. of contact within the receptacle.

fsl. In a, vulcanizer, the combi/nation with a tributing members communicating with the bottom of the receptacle, of a separate re ceptacle adapted to be placed in the main receptacle and to hold a uent fuel when ,the pins when inoperative position.

2.y In a vulcenizer a, receptacle for iiuent 25 fuel, heat-distributing ins-rising lfrom the bottom of the receptac e, and a, removable segmental-shaped cup adapted Ato ft aga-inst the well of the receptacle and to lie below.

3. In a vuloa-nizer, a receptacle' for' lEuent fuel, rows of heat-distributing pins and/a.

removable cup adapted to it in the spee' between the pins and the-wall ofvv-the rece tacle and-to hold a fluent fuelv when the' lvullcanizer is yin f positions othersthn substantially horizontal,

Ini testimony whereof I have hereunto signed my name in the presence of two sub# scribirig witnesses.
